Worker timeout

Hi, could there be an explanation to why my worker is timing out? It is very rare, for example in the last 3 days the worker received 1 million requests and only 54 of them timed-out .

Videos restricted from R2

Hi, I received two emails from Cloudflare regarding Traffic Restriction. However, I am utilizing R2 Storage with a custom domain for my files. I noticed that Cloudflare R2 offers free egress in its features. Therefore, I am unclear about the restrictions I am facing. Could you please help me and assist me in resolving this issue?

Maybe a dumb question, but I can not found the error log

Fresh new for cloudflare, after I deployed, I got a 500 server internal error. 1. After a lot of time of search, I found that I did not not enable web analytics, so i see nothing under Account Home > domain you want to check > Analytics & Logs. 2. After open it, then I stuck at the 500 server internal error shows when I access the site, but in the log, no 5xx code error at all. But I think this maybe because of sample. 3. Then I tried wrangle tail with live debug, but I always stuck at starting local server. when i enter b(browser), d(dev tool) with no response. and a x will response error handle hot key. ...

Sending Early Hints from Workers

Is there a way that I can conditionally send early hints (103) from my workers? I want to preload assets based on request headers and it looks like the Early Hints optimization in the Speed panel will cache the preload hints and serve them for all requests. Is that correct?...

Limit [wrangler:inf] logging without setting --log-level

When developing locally it is super annoying to get the [wrangler:inf] logs all the time, but if I remove them (by setting --log-level) then it disables console.log as well Is there any way to limit these invocation logs locally? I have them disabled in my wrangler.toml, but it doesn't seem to have any effect...

Cache handling for static assets

Hello, I cannot find anywhere how to configure cache headers for static assets under workers. I'm planning to deploy Angular SSR app, obviously there are files like index.html or service worker which should be rather short lived and other that are immutable as build uses hash names. How can I configure this with static assets ? ...

Workers AI Error 429 (3040)

I recently noticed a lot of requests failing to the Workers AI. I looked into it and found out that it is returning a 3040 error. According to the docs this means "No more data centers to forward the request to". I'm using "meta m2m100-1.2b". My Question is if there is any way i can prevent those errors? For example buying the Workers paid plan? Or is that really an Issue with the Workers AI?...

Serve static assets from root path, then handle /api/ requests with my worker?

I was hoping the "Static assets" feature could help me simplify my setup (currently Pages + Workers). I'm having trouble with wrangler dev currently. I want to serve static assets (stored in public directory on filesystem) for every request except for /api/ requests, which my worker should handle.

Workers: Concatenating a large ReadableStream and a footer?

Hey! I have a large document that i get with fetch and i need to pipe it to my client through a response. The file is too large to fit in the worker memory so I am streaming it. Is there any way to concatenate the stream and a footer(for now, 127 null bytes) in a non cpu and memory intensive way?...
